Westbound I-96 is closed at both Kent Lake and Milford Road after a crash that left one truck driver dead, Michigan State Police tweeted on Thursday morning.

At about 5:50 a.m., a semi truck driver moved to the shoulder while experiencing engine problems. A box truck traveling westbound struck the back of the semi.

The box truck driver was killed instantly, while the semi driver did not report injuries, police said.
